the dangerous and wild weather in the west. High winds, flash floods. Ginger zee tracking it all for us. That low started deepening last night. Look at the pictures. This is outside los angeles. You get up to an inch and a half of rain in a place that hasn't had a whole lot. And that goes down. 125-mile-per-hour wind gusts in some of the mountains. It's a deadly mess for the west. Transformers exploding. Flooding. And violent winds, rocking parts of the west overnight. In utah, gusts of up to 80 miles per hour tore at these power lines. The result, transformers flaring. At least three people died in the san francisco area after 50-mile-per-hour winds tossed debris, shutting down interstates. This kind of weather always produces some problems for us because there's so much stuff flying through the air. Reporter: In san diego, at least 300 accidents after heavy rain. Check out this dramatic rescue, when a helicopter is rushed in to help this man. Six, seven feet deep now. Probably went up another four feet. Reporter: Four marines and a cab driver were submerged when the rising water overtook their cab. Fortunately, they were able to climb through a window to safety. So many, counting their blessings this morning, like this guy, whose truck almost drowned in the mud. It was something that happened in a couple of seconds. Some close calls there. And now, that storm is on the move. Look at this. Parts of phoenix could see three to four inches. And some locally, five, six. We could see flash flooding still in california, too. That's the same storm that's going to create some winter weather for parts of texas. And eventually, for us here, next wednesday and thursday. This could be a thanksgiving thunderstorm for us. We'll be looking for that. Wat watching it through the weekend. We needed the rain. Just not that much.
